Question

Alf has four times as many minerals as Jim, and Jim has three times as many as Sid. Altogether they have 192. How many has each?

Answer 1

Answer:

Sid has 12 minerals.

Jim has 36 minerals

Alf has 144 minerals

Step-by-step explanation:

Let the number of minerals that Sid has be x

Thus, based on the question;

Jim has three times the no. of minerals as Sid, i.e., 3x.

Alf has 4 times the no. of minerals as Sid, i.e., 4*3x = 12x

In total, they have 192

Thus,

x + 3x + 12x = 192

16 x = 192

x = 12

Thus, Sid has 12 minerals.

Jim has 3x = 3 x 12 = 36 minerals

Alf has 12x = 12 x 12 = 144 minerals
